EtherCAT communication related alarms are erasable and will not be recorded in

EtherCAT communication alarm however, relies on register clearance from the main
station. Can be solved according to following steps:
1、Set bit 4 of ESC control register 0x120 (error responder) to 1.
2、 The communication alarm can be cleared until the feedback of the ESC status code
register 0x134~0x135 is 0.
3、By setting bit 7 of 6040h to 1, switches state machine from fault to initialization
completion , No fault(Switch on disabled).
